In a much-anticipated move, the California Department of Tax and Fee Administration announced last week that out-of-state retailers who sell above certain thresholds will have to start collecting California use taxes on their sales into the state, starting April 1, 2019.

Since the landmark Supreme Court decision in South Dakota v. Wayfair last finding that out-of-state retailers can be required to collect sales tax, states have been scrambling to come up with new sales tax regimes. California is one of the first big states to announce its policy; other large states like Texas, New York and Florida have yet to weigh in.
